Evaluation of physical findings in acute wrist trauma in the emergency department.
OBJECTIVE: The aim of the study was to evaluate the value of physical findings to predict fracture in patients with acute wrist trauma. METHODS: This prospective clinical study was conducted over a period of four months from December 1998. The patients who were older than 18 years and presenting with acute wrist trauma within 24 hours of the time of injury were included in the study. Magnetic resonance imaging (MRI) was done for the patients who had inconsistency between clinical and radiographic diagnosis. RESULTS: Fifty-five patients were included in the study. Four fractures were diagnosed on the MRI of eight patients who have contradiction between clinical diagnosis and X-ray studies. The positive predictive values of edema, localized tenderness, pain on active and passive motion, pain with grip and pain in supination were found as 95.2%, 67.3%, 77.3%, 91,7%, 89.3%, and 96%, respectively. Physical findings having high sensitivity were found as localized tenderness (94.3%), pain on the active and passive motion (97.1%, 94.3%, respectively). Pain on the active and passive motion were determined as physical findings with highest negative predictive values (%90.9, %89.5, respectively). CONCLUSION: Edema, pain on grip and supination, and especially pain on passive and active motion and localized tenderness can be valuable to predict or rule out fracture in acute wrist trauma cases who have no deformity.
